GEORGE HUNZINGER, OF NEW YORK, N. Y.

CHAIR.

SPECIFICATION forming part of Letters Patent No. 380,629, dated April 3, 1888.

Application filed December 9, 1887. Serial No. 257,433. (No model.)

To all whom it may concern:

Be it known that I, GEORGE Hunzrnenn, of the city and State of New York, have invented an Improvement in Chairs, of which the following is a specification.

Before my invention chairs had been manufactured with the posts or vertical slats of the back-frame and the horizontal rungs or rails united together by inserting the rungs into holes in the posts or slats and gluing the same. Chairs of this character are not strong and reliable, especially in warm or moist climates, in which the glue is liable to become moist or soft or the wood to shrink.

Bymy improvements I am enabled to connect the various portions forming the backframe or the arms, or both, in a very reliable manner without the use of glue and without weakening the strength of the woodwork, as has heretofore been the case by the large holes made use of in connecting one part to the other.

In the drawings, Figure 1 is a side elevation partially in section, and Fig. 2 is a sectional plan at the line a: m.

The seat-frame A is to be of any desired size or character, and it may be caned, upholstered, or otherwise finished.

Myimprovements are especially available in constructing the back and arms; but the same may also be availed of in constructing the legs or supports for the seat. I

The legs, corner posts, or standards B are usually secured to the seat-frame, and they are to be of any desired height. Between these corner posts are slats O, that are nearly vertical and parallel, or nearly so, to the posts B, and these slats C may be more or less numerous, and they may be square, round, or any I prefer to make the same round. The horizontal rails or rungs are composed of sections D, which are usually of wood and tubular, the hole through the same being of a size adapted to receive a wire, E, that is as small as consistent with the required strength and of a length to extend across the back-frame. This wire is preferably round; but it may be a wire or strip of any desired sectional shape.

The lengths of the sections D correspond to the distances between the vertical slats or posts that are to be connected together, and the ends of these sections correspond to the surfaces of theslatsorposts. WheretheslatsGareround, it is preferable to cut off the sections by a revolving or boring tool of the same diameter as the slats, so that the ends of the sections are semicircular concaves that fit against the vertical slats, and these vertical slats are perforated at intervals with holes of a size to pass the wires E at the desired places, so that in putting the chair-back together the wires are passed through the vertical posts and slats and the sections threaded upon the wires, and the ends of these wires are firmly secured, preferably by being cut with screw-threads to re ceive nuts G, by which the parts are tightly drawn up and held together.

I remark that the sections D may be of any desired shape, and they become ornaments between the respective slats, as well as forming firm connections between the parts. Cappieees H may be applied to cover the respective nuts.

The arms of the chair are represented as constructed in a similar manner to the back.

The vertical slats or rungs O are of the proper length, and the sections D and wires E are used to connect the parts, as before described. I have represented ornamental balls I at the bottom of the slats G C and ornaments K at the tops of said slats. These may be either turned up with the slats or rungs or separately attached thereto.

In making the arms of the chair it is advantageous to place the ornaments Kin contact with each other and to passa wire, L, directly through the same transversely and through the respective posts, so as to connect these ornaments firmly together and form arm-rests, and the top of the back-frame may be similarly made, if desired.

I have not represented any legs or supports for the seat-frame, as this chair can be used with a base and rockers resting upon the base, as in my Patent No. 264,880, or any other suitable support may be provided for the seat.

In a chair constructed with my improvements there is greatstrength, and at the same time a small elasticity, that renders the chair very comfortable for use, and the surfaces in contact are drawn so tightly together by the action of the wire and the nuts that noise is entirely prevented, and the creaking usually existing in wooden chairs, especially after a period of use, is avoided, and the wires can be tightened from time to time, if necessary.

I claim as my invention 1. The combination, with the chair-seat, of a back-frame having posts or standards and intermediate slats or posts, and tubular sections between the slats or posts, and wires passing through the posts and intermediate slats and through the tubular sections, the wires being tightened and held in place, substantially as set forth.

2. Thecombination, in a chair, of slats or posts perforated transversely, intermediate tubular sections between the slats or posts,wires passing through the slats or posts and tubular sections and uniting the parts together, and nuts for tightening up the wires, substantially as set forth.

3. The combination, with a chair-seat, of arms formed with vertical slats or posts having ornamental heads perforated transversely and a wire passed through the heads to unite them together, and nuts for tightening the wires, substantially as set forth.

4. The combination, in a chair, ofround slats or posts perforated transversely at intervals, intermediate tubular sections with curved recesses at the ends to fit in between the slats or rungs, wires passing through the respective parts and by which they are strung up, and nuts at the ends of the wires for tightening the same, and cap-pieces covering the nuts, substantially as set forth.

Signed by me this 30th day of November, 1887.
